<P>PROBLEM TO BE SOLVED: To provide a container inner bag having a sufficient strength with a smooth flange surface free from any wrinkles or the like, and a method for using the same. <P>SOLUTION: The container inner bag 1 is formed of a synthetic resin film. A filling port and/or a discharging port of the container inner bag 1 has a flange part 2 of a three-layer structure in which the synthetic resin film to form the container inner bag 1 forms a core layer 21, and synthetic resin sheets 22 and 22' are stuck thereto to hold the core layer 21 from both sides. In the method for using the container inner bag 1 to be attached to a container, the flange part 2 of the container inner bag 1 is attached to the flange part of the container and sealed, and air between an inner surface of the container and the inner bag 1 is discharged in a negative pressure state to prevent the inner bag 1 from falling down. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
